THE FINAL RESULTS
Despite the combo mismatch, on Westech’s chassis dyno the Bronco delivered 338.4 lb-ft at 3,900 rpm, with 269.3 hp on tap at 4,700 rpm. To musclecar guys, these numbers may seem low, but Rhee insists,
“We usually see on trucks with huge wheels and tires, the rearwheel numbers are much lower than the flywheel numbers if the same motor was tested on an engine dyno—mainly due to rolling resistance and tire weight, not necessarily vehicle weight. So, in my experience, you’re really looking at 444 flywheel hp here.”
In any event, the no-longerbucking Bronco now drives smoothly and everything works.
The engine combo could use a larger cam to match the heads. The truck already has steep gears, but there’s still room for growth with a higher-stall torque converter. For Mr. T, the Bronco is everything he wanted and more: “I’m so grateful! I’m overjoyed to see it running.”
